This plant I have carefully eompared with the European C. Soldanella, and with Mr. Brown’s C. reniformis of
Port Jackson and Tasmania, both of which seem one species, and that a very common one on the shores of various
parts of the world. In fruit it is very easily distinguished from C. tuguriorum, the capsule being large nearly a
inch broad, globose, with a stiff point, and containing 1 -3 black seeds, nearly | inch broad. In other’ respects
however, these plants are veiy simüar, and only to be distinguished by the prevailing succulent habit of this, ite
broader, kidney-shaped, blunter leaves, witb rounder deeper sinus, and very rosy flowers.

^ Climbing herbs (rarely erect), chiefly differing from Calystegia iu wanting the bracts below the calyx, and in
having a simple lobed stigma. The species are very numerous indeed, and almost wholly tropical ; t'he’various
kinds of Batatas and Sweet Potato belong to it ; of these the “ Kumerahoa” was found cultivated by Banks and
Solander in tbese islands, as aU over the Pacific, I t is not known where it is a native. (Name derived by Linnæus
from li,, which he erroneously supposed to mean a Convolvulus (but wliioh signifies a worm), aud ôgoioe, like.)

A climbing herb, with five-foliolatc leaves. Leaflets lanceolate, acummate, quite entire, the two outer sometimes
bifid. PeduncUs one- to three-flowered; flowers pendulous. Calyx lobes blunt, much shorter than the tube
of tbe corolla, which is pink, about 14 incb long.—Found also in Australia.

The absence of the two large bracts which include the calyx of Calystegia distinguishes the New Zealand Con-
volvulus. The species of this genus are numerous, and found in all latitudes, except tlie Arctic and Antarctic ;
several are found in Australia and Tasmania. (Name from con and volvo, to twine together.)

I have very indifferent specimens of this plant from Dr. Lyall, and presume it to be that alluded to in
Cunningham’s ‘ Prodromus’ as C. arvensis ? found at the Bay of Islands. So common an Australian plant is very
likely to be a native of New Zealand, especially as it is further very probably identical with the most widely diffused
English, European, and Asiatic C. arvensis, and the same as a South African species that has been published under
several names. Mr. Brown says of C. erubescens, “ Too closely alhed to C. althceoides and C. lanuginosus," both of
them European species ; and neither his description of C. erubescens nor of C. angustissimus (of which he says,
“ præcedenti affinis, an distincta ?” ) includes nearly all the varieties we now know of C. erubescens. This is a point I
shall discuss in the Tasmanian Elora.—A twining or prostrate, slightly hairy or pubescent plant, with stems 4 -1 0
inches long. Leaves oblong or hastate, sometimes linear, entire or three-parted, the lobes very variable in
length and breadth. Peduncles one- to three-flowered, bracteolate. Calyx lobes oblong, blunt or mucronate.
Corolla generally rose-coloured, 4 -1 inch across.

A small, silky, procumbent herb, variable in size, abundant in Australia, Tasmania, and various warm countries
of South America, etc. Stems slender, 3 -10 inches long, sometimes tufted, creeping. Leaves solitary; petioles
ere c t; blade kidney-shaped, quite entire, rounded or notched at the point, more or less silky on both sides, 4-1
inch broad. Peduncles solitary, axillary, about as long as the petioles, without bracts. Flowers small, yellow.
Calyx five-partite. Corolla nearly rotate, having a short tube and flat five-lobed limb. Ovaries two, each cell with
two seeds and one s ty le ; stigmas capitate. Capsules membranous, indehiscent, one-seeded. (Name from Sts-,
double, and xov^pos, a seed)

A very remarkable genus of parasitical, climbing, leafless plants, that germinate in the ground, from a slender
spiral undivided embryo, but whose climbing stems become detached from the root, and derive their nourishment
from little suckers, that penetrate the bark, and come iuto contact with the wood of the plants they grow upon.
